Using Hwa-Lien and Wu-Feng-Shan radar data set respectively, the mean tangential wind component of Nock-Ten has been retrieved by original GBVTD method. It is found that the retrieved maximum mean tangential wind from HL is 14 m s-1 less than that solved by WFS data set. This large difference has been attributed to significant mean wind component perpendicular to the line connecting the radar and the typhoon center.
